Preheat the oven to 400 degrees F. Lightly grease a baking sheet and set aside.
Use a sharp knife to cut the beets and onion into quarters. Place them in a food processor and pulse until roughly chopped. Add the black beans and pulse again until the mixture is sticky and well combined, but not overly processed. You want there to be small chunks of veggies and beans. Stop to scrape down the sides while pulsing as needed.
Transfer the mixture to a mixing bowl and add the eggs, breadcrumbs, paprika, cumin, salt, and thyme. Mix well with a spatula. Roll the mixture into 8 patties about ½-inch thick and place them on the baking sheet. Bake for 15 minutes, flip, then bake for another 5 minutes.
Serve the patties warm on hamburger buns with toppings of choice. Enjoy!
